Homework Help: Algebra

This has me stumped
The approximate time in seconds, that it takes an object to fall d feet under the influence of gravity is given by mathematical model t=square root d/16. A rock dropped from a cliff hits the ground 6 seconds later. How high is the cliff?

or rearranged
distance fallen = 16 t^2

so if t=6
dist = 16(36) = 576

so the cliff is 576 feet high
